If I have understood correctly, the English word "terror" roughly means various activities invoking fear, such as attacks on civilians, and "terrorism" is the use of terror for political purposes. The word "terror" has other meanings as well, but I am only interested in it here as the almost synonym of "terrorism". What would be a good Latin word for this?
The obvious first thought is of course terror, but it seems to mean something else if I read my dictionaries correctly. It means fear or an entity to be feared, not an activity causing fear. One option is to use this old word in an extended sense, but I was hoping there to be something more accurate. I'm looking for a word for modern use, and even coining new words is fine as long as the kind of derivation is attested.
